I can't wait! Weeeeeeeeeeeeeeee!

She’s not revealing many details, but Lauren Conrad says she makes a “life-changing” decision in the season-three finale of MTV’s The Hills, which airs Monday—and she’s happy with the choice she made.
“I gotta be honest, I haven’t seen the final episode yet,” Conrad told PEOPLE at the magazine’s 50th Grammy Awards Kick-Off Party on Thursday. “I know that something happens in our lives, but I don’t know what they’re showing. … Something very exciting happens in my life. I can’t tell you what, obviously, because it has to air, but it was a life-changing something.”
Conrad reportedly is offered a second chance at living in Paris—something she turned down at the end of season one to be with Jason Wahler. Conrad isn’t confirming that, but does say she had a choice to make, and is happy with her decision.
Does it have anything to do with Brody Jenner? “I mean, a little bit, but mostly do to with me,” she says. “I have to make a very big decision—which I made, which I’m very happy with now.”
As the third season wraps, Conrad added that it’s been interesting seeing the viewership change—and even skew a bit older.
“When I did Laguna [Beach], it was all younger, younger kids,” she says, “but most of the people that I talk to (now) are like mid-30s.”
